That's an excellent (I would say must-) read in any case, it documents what
happens when a technical security system designed in a vacuum comes into
contact with the real world.  And by that I'm describing not just the crypto
but also the process for obtaining and maintaining a clearance.  It's one of
the best security usability writeups I've ever read.
